1CY 27C1 28 fax id: 3011 CY27C128 128K (16K x 8-Bit) CMOS EPROM Features Wide speed range 45 ns to 200 ns (commercial and military) Low power 248 mw (commercial) 303 mw (military) Low standby power Less than 83 mw when deselected ±10% Power supply tolerance Functional Description The CY27C128 is a high-performance 16,384-word by 8-bit CMOS EPROM. When disabled (CE HIGH), the CY27C128 automatically powers down into a low-power stand-by mode. The CY27C128 is packaged in the industry standard 600-mil DIP and LCC packages. The CY27C128 is also available in a CerDIP package equipped with an erasure window to provide for reprogrammability. When exposed to UV light, the EPROM is erased and can be reprogrammed. The memory cells utilize proven EPROM floating gate technology and byte-wide intelligent programming algorithms. The CY27C128 offers the advantage of lower power and superior performance and programming yield. The EPROM cell requires only 12.5V for the super voltage, and low current requirements allow for gang programming. The EPROM cells allow each memory location to be tested 100% because each location is written into, erased, and repeatedly exercised prior to encapsulation. Each EPROM is also tested for AC performance to guarantee that after customer programming, the product will meet both DC and AC specification limits. Reading the CY27C128 is accomplished by placing active LOW signals on OE and CE. The contents of the memory location addressed by the address lines (A 0 - A 13 ) will become available on the output lines (O 0 - O 7 ).

For this reason, an opaque label should be placed over the window if the EPROM is exposed to sunlight or fluorescent lighting for extended periods of time. The recommended dose of ultraviolet light for erasure is a wavelength of 2537 Å for a minimum dose (UV intensity multiplied by exposure time) of 25 Wsec/cm2. For an ultraviolet lamp with a 12 mw/cm 2 power rating, the exposure time would be approximately 35 minutes. The CY27C128 needs to be Table 1. CY27C128 Mode Selection within 1 inch of the lamp during erasure. Permanent damage may result if the EPROM is exposed to high-intensity UV light for an extended period of time. 7258 Wsec/cm 2 is the recommended maximum dosage. Programming Modes Programming support is available from Cypress as well as from a number of third-party software vendors.
